Abstract
The invention provides a diffusion transfer receiver comprising a support with a non-light-sensitive image receiving layer coated onto each face thereof, said image receiving layer in each case comprising a catalytic nuclei layer for physical development of transferred complexed silver halide and each composite comprising a diffusion modifying active component which is preferably a tone controlling compound. The composites of Side 1 and Side 2 are different constitutions so as to provide receivers suitable for different end users. For example Side 1 can be made suitable for creative designers while Side 2 can be made suitable for pre-sensitized plate-makers. The invention also provides a method for improving transmission density of a receiver sheet in a non-light-sensitive image receiving layer of a silver diffusion transfer process which method comprises utilizing in the receiver layer an S-thiuronium alkyl sulfonate transmission density enhancer.
